Quick answer
BatchSet's bulk image resizer resizes many images at once — by percentage, a target width or height, or an exact size — free and entirely in your browser, with no signup, upload or watermark. It keeps the aspect ratio (or crop/pad/stretch to an exact size), avoids enlarging smaller images, exports as JPG, PNG or WebP, and lets you download the whole batch as a ZIP. For fixed platform sizes, use the Social Media Resizer.
Three quick steps — free, private, right in your browser.
Drag in as many JPG, PNG, WebP and more as you like — they stay on your device.
Resize by percentage, a target width, a target height, or an exact size (crop, pad or stretch) — applied to every image.
Resize the whole batch in your browser, then download every image as a ZIP.

Drop all your images on this page, choose one resize setting (percentage, width, height or exact size), click Resize all, then download the whole batch as one ZIP. It runs in your browser, so there is nothing to install on Windows or Mac, and it's free with no signup.
There is no fixed limit on the number of images. Each file can be up to 10 MB without an account, or 25 MB with a free account. Very large batches depend on your device's memory, so for thousands of photos, resize them in a few rounds.
Resize to the dimensions you actually need and export at high quality. Downscaling keeps an image sharp; enlarging beyond the original can't add detail, so keep 'Don't enlarge' on to avoid a blurry upscale.
Yes. Resizing by percentage, width or height keeps the aspect ratio automatically, so your images never look stretched. Only Exact size can crop, pad or stretch — your choice.
Yes. Switch to Percentage mode and scale every image to, say, 50% of its original size in one move.
No. Resizing runs entirely in your browser, so your files stay private on your device.
